Comment # 2 on bug 8347 from 
Created attachment 10032 [details]
Capture file for demonstration of Item 53 (Async Negotiation) dissection

With the capture file two things can be demonstrated

a) proper calculation of length for Association Header (packet #1)

- DICOM, A-ASSOCIATE request DCMSND --> DCM4CHEE
  + A-ASSOCIATE request DCMSND --> DCM4CHEE

The whole A-ASSOCIATE-RQ is marked in the lower hexdump window. Without patch
the last 6 bytes were not marked

b) dissection of Async Negotiation

- DICOM, A-ASSOCIATE request DCMSND --> DCM4CHEE
  + A-ASSOCIATE request DCMSND --> DCM4CHEE
    + ...
    + Application Context: DICOM Application Context Name
(1.2.840.10008.3.1.1.1)
    + ...
    + User Info: Max PDU Length 16384, Implementation UID 1.2.40.0.13.1.1,
Version dcm4che-2.0
      + Item Type: User Info (0x50)
      + ...
      + Async Negotiation: Maximum Number Operations Invoked: 0 (unlimited),
Maximum Number Operations Performed: 0 (unlimited)

The Async Negotiation branch is not dissected/shown without the patch.
